BRICK-KILN SPECIFICATION forming part of Letters Patent No. 775,047,dated November 15, 1904.

Application tiled July v18, 1904.

Be it known that we, JOSEPH SONKA and ROBERT A. METZNER, citizens of theUnited States, residing at Seguin, in the county of Guadalupe and Stateof Texas, have invented certain new and useful lmprovementsin Brick-Kilns, of which the following is a specification.

This invention relates to brick-kilns, and particularly to a kilnequally as well adapted for making lime and Portland cement as for themanufacture of brick.

The object of the invention is to provide a kiln of such novel andpeculiar construction and arrangement of parts that a more uniform andequal temperature of the Whole interior is effected and over or underheating is avoided.

A further object of the invention is to provide a smoke-consuming kilnof such special construction that no waste of heat is possible, and theheat is held at ahigh temperature throughout the kiln with the same orless amount of fuel comsurnption as any kiln known to applicants.

A still further object of the invention is to provide in a brick-kilnhaving fire-boxes at each end connected by independant iiues a retractedthroat or passage for the furnace heat in the flues and to prevent draftfrom one fire-box to the other and radial draft passage or ducts fromthe flues through the walls of the latter. f

The object still further of the invention is to provide a kiln the topof which is flush with the ground-surface, affording a solid permanentfloor or driveway, so that loading and unloading may be accomplishedwithout the usual carting or other transportation of the brick to andfrom the kiln.

Other objects, advantages, and improved results are attainable in ourimproved kiln, as will be pointed out in the specification, and

Aset up in the claim to follow.

Brick-kilns, as far as known to us, have the upper half of fire-canalricked up in arch form with inburned brick for each kiln charge, therebyrequiring expert workman to prepare the kiln, and the brick of thearches which receive the heat direct are afterward worthless. Otherkilns require a continued injury to the brick.

Serial No. 217,094. iNo model.)

heat for burning the brick; but according to our invention no such archis required. The fire-arch being permanent and entirely below theHoor-surface permits close approach of wagons or trucks. Thissmoke-consuming kiln permits the fire to be drawn at will without Nospecial or expert workman are required, and greatsaving of brick andtime and labor in handling the same is accomplished.

In the accompanying drawings, forming part of this application, Figurelis a perspective view of part of a kiln embodying our invention andpartly broken away. Fig. 2 is asection on the line aj 90, Fig. l. F ig.3 is a section on the line y y, Fig. 1. Fig. 4 is a section on the linea a, Fig. 3.

The same numeral references denote the saine parts throughout theseveral views of the drawings.

The kiln is composed of the usual number of fire-boxes and iiues and maybe of any desired size or proportions, but for purposes of illustrationonly one pair of re-boxes and iues are shown. The fire-boxes lhaveordinary grates Q, doors 3, and iiues 4, leading from the said boxes andterminating in a contracted throat or passage 5, which preventsthelieat-currents from entering the iiues 4 too suddenly, retards thedraft, and holds the heat-currents in the ues longer than if the flueswere of the same size throughout or if the heat-currents were permittedto enter the flues in full volume from the fire-boxes. The iues as Wellas the fire-boxes are separated by partition-walls 6, extending from oneend to the other of the kiln, and with the arched top of the lu'essupport a permanent kiln-licor 7 which is adapted to have the vehiclesdriven upon it in transporting brick to and from the kiln. The floor 7is provided with heat-discharge apertures 8, between which the brick isstacked upon the ioor for drying and baking. Two sets or rows of theapertures 8 are connected with each of the iues 4 by radial ducts orchannels 9, leading from the flues through the arched top of the fines,so as to distribute the heat-currents throughout the floor-surface.Theducts or channels may be of any desired number or inclination; but weIoo prefer to arrange them at about an angle of forty-live degreesrelative to each other and in rows extending through the ioor of thekiln. lt will be observed that the furnace is below the ground-surface,that the floor 7 is permanent, that the brick to be treated are not usedto form any part of the kiln, so that the usual loss of brick isobviated, and that the kiln consumingsmoke and all particles ofcombustion will permit the fires to be drawn, as desired, during theprocess of cooking the brick without injury to the brick. l

1t is obvious that the iues are built in pairs lengthwise side by side,so that the walls thereofl support a continuous top surface or permanentfloor, and that the furnaces have the usual smoke-stack or chimney andare provided with suitable regulating' devices.

lt will be seen that the heat will be distributed equally throughout thekiln, that the brick are cooked or burned from bottom to top withperfect uniformity, that the arrangement of the heat and draft passagesare such as to reduce loss of heat, and that the ducts terminating in aflat level surface will admit of improved facilities for handling thematerial.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is@ i In a brick-kiln, the combination, withthe walls forming separate flues each of which terminates in acontracted passage central of the flues, and the permanent floor forminga driveway Hush with the ground-surface and having adjacent double rowsof apertures arranged in pairs central of the said walls, of the ductsor channels inclined upwardly and outwardly from each other andconnecting the top of the said iiues with said apertures.

In testimony whereof we afix our signatures in presence of twowitnesses.
